You're looking at them from the "dumb beast" angle, because they replace the animals in the pokémon universe, they must be no smarter than the average animal in our world. Fallacy, every pokémon understands basic commands and the more time it spends with its trainer bonding, grows to understand them better (just as we're shown trainers who've spent years and years with their pokémon being able to understand what they're saying, despite not speaking a recognisable language).
So what do you do after your journey to become the champion has long since ended and you ask your Primarina jokingly why she never sought out a mate and she replies because she's chosen you?
